Fancier theme post background

I’m using the Fancier Theme and have created a customised page template. However, I cannot find a way to remove the black background which appears. I have looked at all the css coding and changed the hex values to ffffff, but nothing works. My website is rudisbalitours.com. If you do a search for say “bali”, the search brings up a page of posts, which a black background. This is what I want to get rid of. I hope someone can assist. I have looked at the Fancier template designer site, but can’t see anything to assist.

Thanking you.
